Unraveling the role of supersulfides in regulating mitochondrial function and longevity      (via sciencedaily.com)     Original source 

Supersulfides, many of which are produced by cysteinyl-tRNA synthetase (CARS), are essential compounds across many different lifeforms. However, the precise physiological roles of CARS-produced supersulfide are unclear. Now, using a strategically engineered yeast mutant with a deficient CARS gene, researchers from Japan have shown that supersulfides control cell longevity by mediating mitochondrial energy metabolism and regulating protein quality.

A novel pathway regulating lipid biosynthesis by fatty acids      (via sciencedaily.com)     Original source 

Sterol regulatory element-binding proteins (SREBPs) play a crucial role in lipid biosynthesis. In a recent study, researchers identified a novel cleavage enzyme of SREBP-1c, a key player in fatty acid biosynthesis. Moreover, the team unveiled, for the first time, that the biosynthesis process of fatty acid in the liver is activated by saturated fatty acids and inhibited by polyunsaturated fatty acids, providing new insights into the intricate workings of this cleavage system.

New rice lines for Africa offer virus protection      (via sciencedaily.com)     Original source 

The so-called Rice Yellow Mottle Virus (for short: RYMV) is responsible for high crop losses in Africa, particularly among small-scale farmers. A research team has now produced rice lines that are resistant to the disease by means of genome editing. The rice varieties are a preliminary step toward being able to generate resistant locally adapted elite varieties for small-scale food producers in Africa.

A new type of plant metalloreductase maintains root growth under low phosphorus      (via sciencedaily.com)     Original source 

Phosphorus is essential for undisturbed plant growth and development. However, in many soils, phosphorus is only poorly available. One mechanism used by plants to increase phosphorus availability is the release of malate, an organic acid, which can form complexes with iron or aluminium in the soil, thereby liberating sorbed phosphate. However, this response can also result in iron overaccumulation, which can inhibit root growth.

Largest diversity study of 'magic mushrooms' investigates the evolution of psychoactive psilocybin production      (via sciencedaily.com)     Original source 

The genomic analysis of 52 Psilocybe specimens includes 39 species that have never been sequenced. Psilocybe arose much earlier than previously thought -- about 65 million years ago -- and the authors found that psilocybin was first synthesized in mushrooms in the genus Psilocybe. Their analysis revealed two distinct gene orders within the gene cluster that produces psilocybin. The two gene patterns correspond to an ancient split in the genus, suggesting two independent acquisitions of psilocybin in its evolutionary history. The study is the first to reveal such a strong evolutionary pattern within the gene sequences underpinning the psychoactive proteins synthesis.
